Ibn Majah

Benefits and Issues:
➊ "He has removed the filth" means that after performing the circumambulation (tawaf) and other rites, he may exit the state of ihram, shave his head, take a ritual bath (ghusl), and wear regular clothes.

➋ For the fulfillment of Hajj, it is necessary to be present at Arafat during the prescribed time.

(1) Perhaps ‘Urwah bin Mudarris radi Allahu anhu did not learn of the announcement of Hajj by the Messenger of Allah sallallahu alayhi wa sallam in time; when he found out later, he set out. Since there had already been a delay, he came directly to ‘Arafat and from there reached Muzdalifah.

(2) “Any hill or mountain”—that is, regarding which it was assumed that staying there was also a part of Hajj, because Hajj was already known among the Arabs and they used to perform Hajj. And the standing at ‘Arafat was an agreed-upon matter; otherwise, it does not mean that starting from the region of Banu Tayy, up to Muzdalifah, they stood on every mountain along the way. This is (practically) an impossible matter.

(3) If a person is unable to come to Muzdalifah at night, then according to some scholars, his Hajj will not be valid. However, the correct view is that the standing (wuquf) at Muzdalifah holds the status of obligation (wujub), as is the position of some researchers. And here, at the very least, performing the Fajr prayer is considered a condition, as is established from another explicit hadith of ‘Urwah bin Mudarris. In it, the completion of Hajj is restricted to standing at ‘Arafat and then catching the Fajr prayer at Muzdalifah, which is evidence for the essentiality (rukniyyah) of the Fajr prayer at Muzdalifah. According to the majority, the standing is obligatory (wajib), but it can be compensated by a sacrificial animal (dam); however, the apparent wording of the hadith is contrary to this. The majority believe that here the negation is not of the genus (i.e., total invalidity) but of perfection. But to interpret this negation as referring to perfection without evidence is against principle. And Allah knows best.

(4) “Removed the dirt and filth”—that is, after stoning (rami) and so on, he will soon become lawful (halal), then he will have his hair cut and will bathe and cleanse himself thoroughly.

624 Lexical Explanation: «من شهد صلاتنا هذه» The prayer (Fajr) for which we have now set out, whoever was present in it.
«ليلا او نهار» In this, a juristic issue is mentioned: that on the day of Arafah, from after the sun passes its zenith until the morning of the 10th of Dhul-Hijjah, whoever stayed in Arafat at any moment during this period has attained Hajj, as Imam Khattabi has said: «فقدتم حجة» “He has completed the Hajj.” This means that he has completed the major part of Hajj. What is meant by this is the standing (wuquf) at Arafat, because there is a fear and concern of missing this, and without it, the major part of Hajj remains incomplete.
«وقضىٰ تفثه» He has removed his filth, meaning he has performed his rites of Hajj. «تفث» These are the acts that a pilgrim (muhrim) does after shaving or cutting the hair of the head, at the time when things become lawful for him. This includes the sacrifice of camels and the performance of all other rites of Hajj, because «تفث» is only completed after this. In origin, «تفث» refers to filth. The beginning part of this hadith is as follows: Hazrat Urwah bin Mudarris radi Allahu anhu said that I came to the Prophet sallallahu alayhi wa sallam at Muzdalifah at the time when you sallallahu alayhi wa sallam were going for prayer. I said: I am coming from the two mountains of Tai. I have exhausted my mount (by making it run) and put myself through hardship. By Allah! I have not left any hill (mountain) except that I have stood upon it (I have stood on all the hills). So has my Hajj been accomplished? Then the entire aforementioned hadith was mentioned.

Benefits and Issues:
➊ “He has removed his filth”
This means that he has completed the rites of Hajj; now, after performing the remaining acts of Hajj, such as Tawaf, etc., he can come out of the state of ihram, get a haircut or shave, take a ritual bath (ghusl), and wear clothes.
➋ For the performance of Hajj, presence at Arafat at the prescribed time is necessary. This is called the standing (wuquf) of Arafah.

Narrator of the Hadith: Hazrat Urwah bin Mudarris—there is a dammah on the “mim,” a fathah on the “dad,” and a kasrah under the stressed “ra.” His lineage is as follows: Urwah bin Mudarris bin Aws bin Harithah bin Lam Tai. He is a well-known companion (sahabi). He participated in the Farewell Hajj (Hajjat al-Wada’). He settled in Kufa. Ten hadiths are narrated from him.

Benefit:
In this hadith, it is mentioned that the pilgrim (haji) will definitely be present in Muzdalifah as well.
